SPACE L-BAND FREQUENCY CONVERTER Satellite communications, earth observation, navigation and positioning and control stations indracompany.com
L-BAND CONVERTER L-BAND FREQUENCY CONVERTER This high performance converter is the most effective solution at a low cost Introduction The 70L500 up- and down-converter is a convenient cost-effective solution with professional-level performance for those systems requiring a 70 or 140 MHz to L-band interface. The independently synthesized up and down converters employ a dual-stage conversion design, providing high-performance over a full 500 MHz bandwidth. Additionally, the up- and down-converters can feed DC power and a 10 MHz reference out to the transmit and receive ports to supply either a phase-locked BUC or LNB. The 70L500 can be combined with most standard solid state power amplifiers, BUC or LNB, providing a high-performance, costeffective transceiver solution for a wide variety of communications systems. The 70L500 can be supplied as a basic module (OEM version) or enclosed in a 1U standard rack, which already includes the power supply module, the 10 MHz internal reference, and interface for monitoring and control.
